摘要
本文用三种有代表性的现代孢粉进行热摸拟实验。实验结果表明孢粉是一种良好的油气生成母质。被子植物花粉生烃能力优于蕨类孢子。同一门类孢粉以个体大,纹饰发育、外壁厚的种类生烃能力好。孢粉素是孢粉热解生烃的主要成分。
Thermal transformation of three types of spora and pollen has been conducted to evalute their generation potential of hydrocarbons.
Experimental results show that the spora and pollen are source of oil and gas generation. Highest oil and gas generating rate of angiosperm pollen are 170mgHC / g Corgand 150ml / g Corgrespectively, and that of herb pteridopgyte spora are 66. lmgHC / g Corgand 11.4ml / g.
300℃ -400℃ are maturational period of hydrocarbon generation of spora and pollen. The thermal degradation of sporopollenin is the major origin of hydrocarbons generation.
Angiosperm pollen is better than herb pteridophte spora in portential of hydrocarbon generation. For same kind of pollen the larger the size of pollen, the better the veins grow, the thicker the outer wall is, the better the generation potential of hydrocarbons.
The contain of asphalt of generated by the three types of sporopollen in thermal degration is higher.
